Diffusion

Collections of Arabic and Greek texts, along with new teaching methods, attracted students from all over Europe to Italy. Once graduated, doctors returned to their home with texts they had studied, and teaching methods they had learned. From Oxford, England in the 13th century to Germany in the 15th, this heritage was assimilated in different ways.

Medical Works at Oxford

The core texts of Salernitan teaching that students brought back to Oxford reflected the cultural diversity of southern Italy. They included classical Greek treatises, introductions to medicine, Byzantine diagnostic booklets, as well as later additions to these major reference works. The following pages from Manuscript 8 of the National Library of Medicine's collection show the diversity of texts included in one book.

Pseudo-Galen, Quid pro quo (Products of substitution).

Substitution was a pharmaceutical procedure that allowed a doctor to substitute a drug that they lacked with another with similar therapeutic effects.

Natural History at Oxford

Oxford teaching integrated the Salernitan medical material with texts by Aristotle. Besides philosophical treatises, Aristotle had written works about natural history, which were called historiai and were collections of data resulting from previous research. Scholars submitted this data to critical analysis, and served as a basis for further work.

Aristotle (384-322 B.C.), De animalibus (On animals).

Aristotle's most important natural history treatise was the Historia animalium (Research on animals), shown here in Latin translation.

A Method of Teaching

The Oxford teaching method was based on careful scrutiny of texts aimed at distinguishing from one another all cases discussed in the works under analysis. As a result, textual data was organized so as to form hierarchical trees formalized in books, according to an analytical method perhaps rooted in the Arabic tradition.

Germany

In Germany, texts of different origins were grouped. The gynecological booklet ascribed to Cleopatra appeared together with works by such Arabic scientists as Mesue, Albucasis, and Rhazes, and with a more recent treatise by the Italian Marsilio de Santa Sofia (d. 1405), as well as with contemporary anonymous tracts on plague and leprosy, and a lexicon of plant names.

Anonymous, Synonima [herbarum] (Plant names).

This lexicon contains Latin phytonyms with their German translation. This suggests that learned medicine was integrated into the daily practice of German-speaking doctors.
